### Auto Sphere Construction

The following list indicates the type of sphere that PC-DMIS constructs when you select the specified inputs and choose the Auto option. The order of the selected features is not important. If you choose an incorrect input feature, PC-DMIS displays an error message and does not automatically construct the indicated feature type.

Four or more Features = Best Fit Sphere

Any one Feature (except Sphere/Set) = Cast Sphere

Any one Set = Best Fit Sphere

Plane + Any Feature = Project Sphere

Sphere = Reverse Sphere

To allow PC-DMIS to automatically determine the best method of construction:

1. Access the Construct Sphere dialog box (Insert | Feature | Constructed | Sphere).

2. Select the Auto option from the list of options.

3. Select the desired feature or features.

4. Click the Create button.
